Abstract (en)
An x-ray detector includes a two-dimensional array (100) of detector elements that is segmented into regions (102). The detector elements (104) in each region may be separately gated, or may be gated in blocks of elements to read out data onto a common data line to a region pre-amplifier (106). A scan sequencer (110) operates the gate control lines (108) to perform a scan in which the spatial resolution of the data read out from each region of the detector array may be separately selected to optimize the x-ray detector for particular clinical applications. <IMAGE>
